    Route discovery process is a major mechanism in the most routing protocols in Mobile Ad Hoc Network (MANET). Routing overhead is one of the problems caused by broadcasting the route discovery packet. To reduce the routing overhead, the location-based routing schemes have been proposed. In this paper, we propose our scheme called Location-based Routing scheme with Adaptive Request Zone (LoRAReZ). In LoRAReZ scheme, the size of expected zone is set adaptively depending on the dis-tance between source and destination nodes. Computer simulation has been conducted to show the effectiveness of our propose scheme. We evalu-ate the performances of LoRAReZ scheme in the terms of packet delivery fraction (PDF), routing overhead, average end-to-end delay, throughput, packet collision, average hop count, average route setup time, and power consumption. We compare those performance metrics with those of Lo-cation Aided Routing (LAR) and Location Aware Routing Protocol with Dynamic Adaptation of Request Zone (LARDAR) protocols. The simula-tion results show that LoRAReZ can provide all the better performances among those of LAR and LARDAR schemes. © 2013 The Institute of Electronics, Information and Communication Engineers.

    In this paper, we present the impact of mobility on our scheme called Location-based Routing with Adaptive Request Zone (LoRAReZ). In LoRAReZ, the size of expected zone and request zone are set adaptively based on the distance between the source node and destination node. We evaluate the impact of mobility on the performance of LoRAReZ in terms of packet delivery fraction, routing overhead, end-to-end delay, throughput and power consumption by comparing with those of the traditional Ad Hoc On-Demand Distance Vector (AODV) and Modified Ad Hoc On-Demand Distance Vector (MAODV). The results show that LoRAReZ can provide the better performance than those of AODV and MAODV. © 2012 IEEE.
